BLIND-NAIL-TRIMMING I STRIP.

Application filed'April 26, 1924.

To all whom it may concern:

Be it known that I, ALBERT'L. HOWARD, a citizen of the United States, residing in Brockton, int-he county of Plymouth and State of Massachusetts, have invented an Improvement in Blind Nail Trimming Strips, of which thefollowing description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates .to 'a blind nail trimming strip of that character in which plurality of beads are employed, and has for its object to provide a superior trimming stri of the character specified, which is es peclally adapted among other uses to be employed for trimming automobile and like bodiw.

To this end, the trimming strip is provided with a relatively wide bead which is movable about one side edge as a pivot to cover and uncover the nailing strip and afford a wide opening or space for the insertion of the tacks or nails into the nailing strip, and is further provided with a plurality of relatively smaller beads which are located at the opposite side of the nailing strip and are connected together to form a side flap which co-operates with the wider bead in the closed position of the latter, to lock the latter down upon the nailing strip against accidental displacement and thereby ensure the trimming strip retaining the desired three beaded effect in use. 7 v v p The smaller beads are arranged as will be described, so that the inner bead constitutes a locked bead for the wide bead and the outside bead constitutes a pivot for the locking bead and is constructed and arranged with relation to thelocking bead and to the nailing strip so as to permit the side flap and its locking bead to be lifted and turned back to uncover the nailing strip and to thereby increase the width of the opening through which accem is had to the nailing strip.

The smaller beads are arranged with relation to the nailing strip, sothat when the latter is nailed or tacked to the surface to which it is applied, the side flap is moved or drawn down'by the nailing strip into its looking position, in which the locking bead thereof overlaps and bears upon the Wider Serial No. 709,176.

bead The wider bead may, and preferably Wlll be provided on its inner side with a pro jecting flange or lip which is extended under the looking bead in the closed position of the -embodying this invention.

Fig. 10 a view like Fig. 9 on an enlarged scale.

Referring to the drawing, and especially Fig. 10, ((4) represents the wide bead, (b) a small or narrow edge bead, and (0) a small or narrow locking bead. The wide bead (a) may and preferably will be made substantially semicircular and provided with a substantially straight lower surface 10 which is preferably of width greater than one-half of the width of the finished trimming strip. The beads (79), (0) are preferably circular and relatively smaller than the wide bead (a). The heads (a), (b), and (0) are enclosedin a covering strip (d) of leather or other suitable material, which strip is of sufficient width to envelop the beads (a), (b), and (0), and is cemented or otherwise secured thereto.

The covering strip (d) is also preferably of sufficient width to be folded upon itself and form a flange or, lip 12, whichprojects from one edge of the wide bead and which edge forms the inner edge of the bead (a) when the latter is in its closed position shown in Figs. 1, 9, and 10.

Figs. 3 to 6 illustrate a method of forming the trimming strip, which is as follows: The covering strip ((5) is developed or laid out flat and the beads (a), (Z2) laid thereon, after which the side portions of the covering strip are folded over to envelop the beads (a), (b), and are cemented thereto. The head (0) is then laid upon the covering strip (d) adjacent to the head 2) but separated therefrom as shown in Fig. t, after which the side of the covering strip carry-- ing the head (5) is folded about the head (a) as represented. in F ig. 5, and the folded over portion 13 of the covering strip is then secured to the underlying portion 14 by a row o f-stitches 15, which are located between the heads (a), as represented in Fig. 6. A trimming strip in an opened up or developed condition is thus formed. which provided on one side of its longitudinal. center with wide bead (a) and 'on the other side of said longitudinal center with a. side flap composed of two relatively small. beads, (Z1), (0) and the portion of the covering strip which envelops them, which side flap is separated from the wide bead but COIlIIQCt ed therewith by a relatively wide section or portion 20 of the covering strip, which sec tion or portion 20 forms the bottom member or nailing strip of the finished trinn'ning strip, through which tacks or nails 21. are driven into the automobile body or other object to which the trimming; strip is ap plied. The wide bead (a is then folded over upon the nailing strip 20 and its inner edge, which in the. present instance is provided with the flange or lip 12, is passed. or tucked under the locking bead represented in Figs. 9 and 10. y

The locking head (0) is drawn down upon the inner edge portion of the wide bead (c) and serves to hold or look the latter bead down upon the n ailing strip until positively released by the operator, which assures the beads being retained in their desired position against accidental displacement.

When the trimming strip is to be nailed to the automobile body or other object, the side flap is lifted up by the operator so as to move the locking head 0 and uncover the wide head (a) and render the latter accessible to the operator, who turns'it in the opposite direction and into the position shown in Fig. 7. When the locking head (a) is lifted and turned back from the position shown. in Fig. 9 into that shown in Fig. 7, the side flap is turned on the bead. (Z as pivot and the side or portion of the nailing strip 20 attached to the heads (2')), (c) is lifted away from the object to which the trimming strip is to be attached, which object is represented by the line 30. The widebead is free or unrestrained to be turned about its outer edge as a pivot into a position beyond a vertical plane through the said edge as shown in Fig. 8, and thereby obtain an opening between. the head (a) and the lock head (a) which is of greater width than the nailing strip 20, which allows the operator opportunity to properly nail the nailing strip 20 to the object. By reference to Fig. 8, it will be observed that when the nailing strip 20 is nailed to the object,

the said strip acts to turn the side flap about the edge. bead (b) as a pivot and to pull or draw down the locking head (0) toward the nailing strip and to hold it there until it is raised by the operator sufficiently to enable the wide bead (a) to be turned into its closed position, shown in Figs. 9 and 10, in which its inner edge is beneath the lockinghead (a), and when thus positioned, the lifting, force is removed from the locking head (0) and the latter is drawn down by the. nailing strip upon and in contact with the wide bead a), which is overlapped by the locking bead and firmly locked or held down against accidental displacement. It will also be observed that when the trimming strip is nailed or tacked to the automobile body or other object to which it is fastened, the outer beaded edge of the side flap is held, in firm contact with the said body or object and offers material resistance to pivotal movement of the side flap, which assists in the locking of the wide head by the inner edge head 0 of the side flap, and requires positive action on the part of the operator to turn back the side flap, and as a result accidental turning back of the side flap and unlocking of the large head is prevented. As a result an attractive, distinctive, and finished three beaded trimming strip is obtained in which the heads have a close relation, which is preserved in service.

It is preferred to provide the large head a with the lip 12, as the latter assists in moving the side flap and holding the head (i in its locking position. for when the strip is being; attached. to the body 30, the large head a is turned into its closed position and the lip 12 is tucked under the locking bead c and bears on the nail-receiving portion 20 in close proximity to the stitches 15, so that when the tack 21 is driven into thebodv 30. the nail-receiving portion 20 is placed under tension and pulled down and at the same time the head 0 bearing on the lip 152 arises the latter to exert a downward upon the nailing strip, which increases the locking effect of the head 0 of the side flap.

VVh-at I claim is:

1. A blind nail trimming strip compris ing a covering strip having a nail. receiving portion, a relatively wide bead connected to the said coverinp; strip with its outer edge on one side of the said nail. receiving por tion, to pivot on said outer edge when moved into its closed and open positions, a plurality of smaller beads located on the opposite side of the nail receiving portion and connected with the covering strip in close relation to each other to form with said covering strip a relatively stifi side flap having inner and outer edge beads, said side flap being arranged with relation to said nail re ceiving portion to turn on said outer edge bead as a pivot and to have its inner edge bead overlie the wider bead in the closed position of the latter, and means for connecting said nail receiving portion with said side flap between said small beads to cause the nail receiving portion when nailed to its support to turn the side flap as one piece on the outer bead as a pivot and to draw the inner edge bead down onto said wide bead and thereby lock the latter in its closed position and to cause the outer edge bead to ofler material resistance to the opening o1 said side flap.

2. A blind nail trimming strip comprising a covered strip having a nail receiving port-ion, a relatively wide bead connected to the said covering strip with its outer edge on one side of the said nail receiving por tion, to pivot on said outer edge when moved into its closed and open positions and having its inner free edge provided with a lip or flange, a plurality of smaller beads located on the opposite side of the nail receiving portion and connected with the covering strip in close relation to each other to form with said covering strip a relatively stiff side flap having inner and outer edge beads, said side flap being arranged with relation to said nail receiving portion to turn on said outer edge bead as a pivot and to have its inner edge bead overlie the wider bead in the closed position of the latter, and means for connecting said nail receiving portion with said side flap between said small beads to cause the nail receiving portion when nailed to its support to turn the side flap as one piece on the outer bead as a pivot and to draw the inner edge head down onto said wide bead and thereby lock the latter in its closed position and to cause the outer edge bead to ofi'er material resistance to the opening of said side flap.

3. A blind nail trimming strip compris ing a covering strip having a nail receiving portion, a substantially semicircular wide bead connected at its outer edge to said covering strip atone side of the said nail receiving portion to pivot on said outer edge, and a plurality of substantially circular smaller beads connected with said covering strip to form a side flap having inner and outer edge heads at the other side of the nail receiving portion, said side flap being arranged to pivot as one piece about the outer small edge bead when moved away from the nail receiving portion and to have the inner small edge bead overlie the inner edge of the wide bead and lock the latter in its closed position when the said side flap is moved toward the nail receiving portion, and means for connecting the said side flap between its outer and inner edge beads with said nail receiving portion.

41. A blind nail trimming strip comprising a covering strip having a nail receiving portion and a plurality of beads connected with said covering strip and comprising a relatively wide bead connected with the covering strip at one side of the nail receiving portion, and a plurality of smaller beads connected with the covering strip to form a relatively stiff side flap at the other side of; said nail receiving portion, said side flap being arranged to pivot as a unit about one of its beads and to have another of its beads overlie the free inner edge of the wide head in the closed position of the latter to lock the wide bead in its closed position.

5. A blind nail trimming strip having a relatively large bead, a plurality of relatively smaller beads located at one side of said large head, a covering strip having one side portion thereof secured to said large bead to permit the latter to be turned upon the outer longitudinal edge thereof as a pivot, and having its other side portion secured to said smaller beads to form therewith a side flap provided with beaded inner and outer edges and capable of being turned about the outer bead as a pivot and having the inner bead thereof capable of materially overlapping the large bead, said covering strip having a nail-receiving portion between said side flap and the outer edge of said large bead, and means to secure said side flap to said nail-receiving portion and cause the latter to exert a downward pull upon the said side flap when the trimming strip is nailed in position and to cause the outer head to offer material resistance to the opening of said side flap.

6. A 'blind nail trimming strip having a nail-receiving portion, a relatively large bead cooperating therewith, a side flap having an outer and an inner relatively small edge bead and movable as one piece about said outer bead as a pivot and cooperating with said large bead to have its inner small bead overlap said large head in the closed position of the latter, and connected with said nail-receiving portion to be pulled downward thereby and cause said inner smaller bead to lock the large head in it closed position and to cause said outer bead to resist opening of said side flap, said inner and outer beads also serving to prevent puckering of said trimming strip when curved.

7. A blind nail trimming strip having a nail-receiving portion, a relatively large bead cooperating therewith and provided with a side lip, a side flap having an outer and an inner relatively small edge bead and movable as a unit about said outer head as a pivot and cooperating with said large bead to have its inner small bead overlap said large bead and engage the lip thereof in the closed position of said large bead, and connected' with said nail reoe iving portion to be pulled down thereby and cause the inner small bead to lock the large bead in its closed position and to cause said lip to exert pressure upon said nail-receiving portion and assist in looking said large bead.

In testimony whereof, I have signed my name to this specification.
